BleepingComputer.com: Trying to organize my music

Im trying to organize my music collections and want to organize everything by Artist/Album. I tried going though and editing all the files myself but that took way to long (gave up after one cd) and was wondering if there was a program that could go out to the CDDB and look up the song title and edit the file to add the Artist and Album. I have many songs that have been downloaded off of p2p programs i.e. kazza, limewire, iMesh, etc. If anyone knows of a easy way to do this or a good program preferably freeware but i am willing to pay plz let me know thanks.

I use MediaMonkey to organize music. You can auto-tag from the Amazon database and also automatically change the filenames after you change the tags. I would use WMP or something to play them though because the built in audio player isn't all that great IMO.
